Frequently Asked Questions
Can I use the RPS-120S-12 for a 12V industrial PC or embedded controller?
Yes, if the equipment needs a constant 12V DC input and draws no more than 9.5A. With a 114W rating and 80-264VAC input range, it suits many embedded and industrial control applications powered from AC mains.
Is the RPS-120S-12 suitable for 12V automation peripherals and I/O hardware?
It can be used with 12V automation peripherals or I/O hardware that require a stable constant voltage source. The output is 12V at up to 9.5A, so the total load must remain within 114W.
Can this model power medical 12V electronics?
The product is a medical power supply and carries CB, CE, cUL, EAC, and c_shide certifications. It is suitable where the equipment requires 12V constant voltage up to 9.5A and where those approval needs matter.
Is the RPS-120S-12 a good fit for compact equipment designs?
It is notably compact at 76.2 × 50.8 × 28.0 mm and weighs 0.13 kg. That makes it attractive for equipment designs where internal space is limited but the load still needs up to 12V and 9.5A.
Can the RPS-120S-12 handle hot or cold operating environments?
Its operating temperature range is -30°C to +85°C, which is wider than many enclosed power supplies in this wattage range. No IP rating is listed in the provided data, so the specs do not establish outdoor exposure suitability.
How does the RPS-120S-12 compare with the other RPS-120S models?
The RPS-120S family includes RPS-120S-12 at 114W, 12V, 9.5A; RPS-120S-15 at 114W, 15V, 7.6A; RPS-120S-24 at 120W, 24V, 5A; RPS-120S-27 at 119.9W, 27V, 4.44A; and RPS-120S-48 at 120W, 48V, 2.5A. Compared with the standard RPS-120-12 and RPS-120-12-C at 84W and 10A, this model is the higher-power 12V option within the same general series range.
